Detailed description of the invention
As shown in Figure 1, the utility model is used for the quick-replaceable bracing or strutting arrangement of large_sized hydraulic cylinder and comprises lower dull and stereotyped 1, two blocks of side plates 11, V-arrangement back-up block 2, two wheel shafts 12, four rolling 13, flange seat 3 and elevating mechanism 4, described lower dull and stereotyped 1 both sides, bottom surface are located at by described two blocks of side plates 11 respectively interval vertical, described two wheel shafts 12 penetrate the two ends of described two blocks of side plates 11 respectively, described four rolling 13 is located at the two ends of described two wheel shafts 12 respectively, described flange seat 4 is located at described lower dull and stereotyped 1 end face, described elevating mechanism 4 is located between described flange seat 3 and V-arrangement back-up block 2.
Further, the wheel face of described four rolling 13 is respectively equipped with step 14.The step of roller wheel face facilitates it to advance on track or H profile steel, plays the effect of location, avoids roller to derail.
Further, this bracing or strutting arrangement also comprises some deep floors 5, and described some deep floor 5 intervals are symmetrically set between described flange seat 3 wall and lower dull and stereotyped 1.Preferably, four pieces of deep floors can be adopted to be symmetrical arranged along flange seat wall side face, thus to improve the rigidity of this bracing or strutting arrangement.
Further, as shown in Figure 2, described elevating mechanism comprises hoist cylinder 41 and self-aligning thrust roller bearing 42, the cylinder barrel of described hoist cylinder 41 is vertical in the middle part of described flange seat 3 end face, and piston rod 43 top of described hoist cylinder 41 is located in the middle part of described V-arrangement back-up block 2 bottom surface by described self-aligning thrust roller bearing 42.When piston rod and self-aligning thrust roller bearing are installed, piston rod top is provided with step, self-aligning thrust roller bearing inner ring is withstood by the shaft shoulder of step, thrust force aligning roller bearing inner ring can fill the axle sleeve with step, axle sleeve one end is connected with piston rod top, the other end is inserted in thrust force aligning roller bearing inner ring, realizes the connection of piston rod and self-aligning thrust roller bearing.The sleeve length of this connected mode can compensate the deficiency of hoist cylinder stroke, realizes the support to changing hydraulic cylinder.
Further, as shown in Figure 3 and Figure 4, described elevating mechanism comprises two adjusting nuts 45, locking nut 46, screw rod 44 and self-aligning thrust roller bearing 42, described flange seat 3 end face center is provided with screw, described screw rod 44 bottom is twisted in the screw of described flange seat 3 end face, described two adjusting nuts 45 and locking nut 46 are twisted respectively on described screw rod 44, described two adjusting nuts 45 are locked mutually, described locking nut 46 is positioned at described flange seat 3 end face, described screw rod 44 top is located in the middle part of described V-arrangement back-up block 2 bottom surface by described self-aligning thrust roller bearing 42.
Further, this bracing or strutting arrangement also comprises pressing plate 6 and sealing ring 7, and described V-arrangement back-up block 2 bottom surface is located at by described pressing plate 6, and described sealing ring 7 is located between described self-aligning thrust roller bearing 42 and pressing plate 6.
This support device structure is simple, flexibly mobile, take up an area little, simple and efficient to handle, comparatively large for cylinder body volume, that piston rod length is longer, assembling fit clearance is less hydraulic cylinder changing is quite effective, by V-arrangement back-up block, hydraulic cylinder body to be replaced is provided support and position adjustments, movement can the moving direction of hydraulic control cylinder on horizontal guide rail for the roller of lower flat plate bottom, thus can dismantle easily and install when ensureing hydraulic cylinder changing, improve dismounting and the installation effectiveness of hydraulic cylinder, effectively solve the replacing problem of overlength hydraulic cylinder.
When changing hydraulic cylinder, guide rail is set up below hydraulic cylinder, and the axis direction passed in and out when being adjusted to hydraulic cylinder changing, the four rolling of this bracing or strutting arrangement is placed on guide rail, the step of roller is against guiding edge, roller is avoided to derail, the height of V-arrangement back-up block and the axial location of hydraulic cylinder dismounting is regulated by elevating mechanism, hydraulic cylinder is positioned in the v-depression of V-arrangement back-up block, then the securing member of dismounting hydraulic cylinder, hydraulic cylinder can be moved into or shift out installation site, the moving direction of hydraulic cylinder is consistent with orbital direction, thus when avoiding hydraulic cylinder to dismantle and install, adopt the catching phenomenon that the pulling force of chain block imbalance causes.
Elevating mechanism in this bracing or strutting arrangement can adopt hoist cylinder, and hoist cylinder is located between lower flat board and V-arrangement back-up block, can realize lifting by convenient, fast drive V-arrangement back-up block.Elevating mechanism also can adopt screw-rod structure, screw rod bottom is twisted in the screw of flange seat, screw rod can be driven to rotate by two adjusting nuts of mutually locking, screw rod bottom can be stretched in flange seat, thus regulate the height of V-arrangement back-up block, realize the lifting of V-arrangement back-up block, regulate the complete locking realizing screw position by locking nut screwing flange seat end face.Hoist cylinder piston rod top or screw tip connect V-arrangement back-up block bottom surface by self-aligning thrust roller bearing, make V-arrangement back-up block have certain free degree, facilitate the adjustment in hydraulic cylinder direction in hydraulic cylinder changing operation.In addition; in V-arrangement back-up block bottom surface, pressing plate is set; between pressing plate and self-aligning thrust roller bearing, sealing ring is set; thus provide effective protection to self-aligning thrust roller bearing; avoid the impurity such as production scene dust on the impact of self-aligning thrust roller bearing, guarantee the flexibility that V-arrangement back-up block is connected with hoist cylinder piston rod top or screw tip and reliability.
